SealLine BlokerLite Details:

Seal Line's lightest, most efficient-packing dry sack, the ultralight BlockerLite boasts a patent-pending rectangular shape and strong fully welded seam construction to deliver waterproof protection while organising clothing and gear in your pack.

Space-saving: Patent-pending rectangular shape packs 20% more efficiently than rounded dry sack shapes, saving space in your pack.
Efficient-packing: PackTight™ packing system takes advantage of the flat-sided, rectangular shapes of the BlockerLite dry sacks, closely nestling them together for an easy, space-saving and intuitive organisation.
Waterproof strength: 50% stronger than sewn and taped seams, all seams are welded to deliver superior strength, durability, and waterproof protection.
Ultralight: Featherweight 20-denier silicone- and polyurethane-coated nylon delivers waterproof protection while barely tipping the scales.
Eco-friendlier: PVC-free materials offer a reduced environmental impact over vinyl materials.
Secure: Roll-top closure features a grippy stiffening strip to ensure a wrinkle-free, secure seal when closing the dry sack.
Easy organisation: Available in 4 colours and 5 sizes, making it easy to organise by both dry sack colour and size.
